Application of power adapters
Power adapter is widely used in industrial automation control, military industry equipment, scientific research equipment, LED lighting, industrial control equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps and lanterns, communications equipment, audio and video products, security, computer case, digital products and equipment, and other fields, and in these areas have the effect that cannot ignore. What are the functions of a power adapter?
The role of the power adapter
Generally speaking, the power adapter ACTS as a transformer and a rectifier. Ac power at home is 220v, while our computer USES 12v dc (as it were), so we can be sure that the power adapter is the transformer and rectifier. The adapter is a transformer, so we should know, ac 220v through the transformer transformer voltage, through the rectifier dc, there is consumption, and these consumption will be converted into heat, so it is normal that the power adapter will heat up. The transformer is made of silicon steel sheet. After the transformer is energized, the magnetic flux will be generated. The magnetic flux will lead to the action of force between the silicon steel sheet and the buzzing sound, which is normal. But the overheated sound is abnormal for a number of reasons: the alternating current voltage is unstable; Chip damage; Interturn short circuit; Component damage, etc. An adapter,
